Did you know stainless steel can still corrode? đź‘€
Stainless steel gets its corrosion resistance from a thin, chromium-rich oxide layer—but manufacturing can leave free iron and other contaminants on the surface.
That’s where passivation comes in. The process removes surface contaminants and helps strengthen the protective chromium oxide layer, improving corrosion resistance without changing the part’s dimensions.
But nitric acid, citric acid, and electropolishing don't all work the same way.
So which passivation method is right for your stainless steel parts?
We break down the differences in our latest article. 👇
